When Natalie Portman signed on to play Mathilda in “Leon: The Professional,” her parents insisted on a clause limiting the amount of swear words she was allowed to say. For the big screen adaptation of the comic book “Kick-Ass,” it seems that Chloe Moretz’s parents didn’t do the same.

Twelve-year-old Moretz plays Hit Girl--and in her teaser trailer alone, she drops the f-word and the c-word, chops some legs off and shoots more bad guys than you can count. Maturity suits Moretz well, however. Her role in “(500) Days of Summer” as the extremely adult, fast-talking kid sister of Joseph Gordon-Levitt was one of the most enjoyable, albeit unbelievable, parts of the film.

The new Red Band trailer for “Kick-Ass,” which focuses on Hit Girl, already has sent a firestorm through geek blogs everywhere. In our age of political correctness and Disney values, a swearing, murderous pre-pubescent girl is certainly an anomaly--and a hilarious one at that. The trailer doesn’t tell us too much about the other characters or plot of the film, but we do see Nicolas Cage taking a back seat to Moretz’s star power as the father of the junior assassin. British actor Aaron Johnson plays title character Kick-Ass, and an unseen Christopher Mintz-Plasse (“Superbad”) takes on Red Mist. But the real question on everyone’s mind is this--is it too much? A cussing, occasionally school-girl outfit-clad tween heroine?
